Are harley Davidson dyna glides a good beginner bike?

No. The Dyna Glide is a fairly large-engined motorcycle, typically 88ci (1450cc) or larger. This is a lot of weight and power for a beginning rider. It is better than some Harley Davidsons in the sense that it is a fairly stripped-down design without fairings or a lot of dress accessories, but typically a beginning rider should start on a much smaller motorcycle.

Depending on how big of a person you are, a lightweight cruiser or street-type motorcycle in the 250cc to 600cc range would be ideal. Racing bikes and larger-displacement bikes are more likely to result in fear, frustration and possible injury. Also, most states require you to take a riding test on a motorcycle you provide in order to get a license. This test is typically significantly easier to pass on small motorcycles.

As far as Harley Davidsons go, the best motorcycle for a beginner would be the 883cc Sportster, although that can still be a lot of bike, particularly for someone small.
